ANALYSIS: Adrian Peterson's (neck) surprise inactivity in Week 13 opened the door for Williams, who ran 16 times for 97 yards. He wasn't involved in the passing game. Williams' fantasy ceiling remains limited, though, as he's not much of a pass catcher, and he hadn't seen more than three carries in any game before this.

The Rams don’t have a great rush defense compared to a stout secondary, but it’s still encouraging to see this out of Williams considering his 69 total rushing yards on 28 carries on the season leading up to the game.

The Cardinals are being extremely tight-lipped on the severity of Peterson's neck injury, so there's a chance he'll miss a second straight game. Against the Titans in Week 14, Williams would be an RB3/flex option in deep standard-scoring leagues if he sees another start.
